Properties of Galactic Globular Clusters
We have assembled 560 recent measurements from the literature of distances of Galactic globular clusters and found revised distance estimates for 154 of the 157 clusters in the... -
The Cluster System of the LMC
A new catalogue of clusters in the Large Magellanic Cloud has been constructed from searches of the IIIa-J component of the ESO/SERC Southern Sky Atlas. The catalogue contains... -
Structure Parameters of Galactic Globular Clusters
This catalog contains observed and derived structure parameters for 154 galactic globular clusters, 7 dwarf spheroidal satellites of the Galaxy, and 6 globular clusters in the... -
Updated catalog of variable stars in globular clusters
This Catalogue is an update to Helen Sawyer Hogg's Third Catalogue on Variable Stars in Globular Clusters (1973, David Dunlap Observatory Publications, Volume 3, Number 6:... -
Revised Bologna Catalog of M31 clusters, V.5
The dataset lists all the confirmed globular clusters (GC), all the known candidates GCs, and also all the objects that were identified as candidate GCs in the past and were... -
Globular clusters as gravitational lenses
Based on the SDSS catalog, we have found new close quasar-galaxy pairs. We analyze the radial distribution of quasars from pairs around galaxies of different types. We show that... -
Identification and coordinates in M 53
Equatorial coordinates have been determined for 61 variables in the northern globular cluster M 53 and for 12 variables in the southern globular cluster NGC 2808 with accuracy... -
Identification and coordinates in M4
Accurate equatorial coordinates have been determined for 54 variable stars in the globular cluster M 4=NGC 6121. Cone search capability for table J/PAZh/22/847/table12... -
Photometry of the globular cluster NGC 6139
Photographic BV photometry has been performed for stars in the southern globular cluster NGC 6139. Equatorial coordinates have been determined for the ten variables recognized... -
Giant branch and variable stars in NGC 3201
Accurate equatorial coordinates have been determined for variable stars in the globular cluster NGC 3201. Results of photographic BV photometry are presented. Cone search... -
BVR photometry of NGC 6584
Automatic stellar photographic BVR photometry reaching 1mag below the horizontal branch of NGC 6584, located at V~16.5mag, has been performed for this poorly studied globular... -
Identification and coordinates in M5
Accurate equatorial coordinates have been determined for 143 variable and suspected variable stars in the globular cluster M5=NGC 5904. For 28 stars, identifications with... -
Identification and coordinates in NGC 5272
Equatorial coordinates of variable stars in the globular cluster M3 (NGC 5272) and its nearest surroundings, mainly measured on a plate taken with The Zeiss-1000 telescope, are... -
BV photometry in 4 fields of 47 Tuc
CCD photometry in B and V, taken with the RCA camera at the CTIO 4-meter telescope, is reported for 8800 stars in the field of 47 Tuc (= NGC 104 = C0021-723). Our data, reduced... -
Compact star clusters in SW field of M31
A survey for compact clusters with a dimension of 10pc order was conducted in an area of about 500 square arc-minutes of the south-west part of the M31 disk, making use of the... -
Chandra compact binaries in 47 Tuc
We have obtained high-resolution (<~1") deep X-ray images of the globular cluster 47 Tucanae (NGC 104) with the Chandra X-ray Observatory to study the population of compact... -
NGC 1851 variables light curves
We report VI CCD photometry of the globular cluster cluster NGC 1851. We aim to study the membership of the variable stars detected in the field of the cluster as listed in the... -
NGC 1261 variables VI light curves
Time-series VI CCD photometry of the globular cluster NGC 1261 is employed to study its variable star population. A membership analysis of most variables based on Gaia DR2... -
Variable stars in NGC 6934
We report an analysis of new V and I CCD time-series photometry of the globular cluster NGC 6934. Through the Fourier decomposition of the RR Lyrae light curves, the mean values... -
RR Lyr light curves in NGC 3201
CCD time-series observations of the central region of the globular cluster NGC 3201 were obtained with the aim of performing the Fourier decomposition of the light curves of the...
